Now used by businesses globally.
No installation. Just turn it on to start purifying the air
Mounted on caster wheels makes it easy to move
Intelligent sensors adjust level to surrounding air particles
Maintains low noise levels despite a powerful motor
The Rensair air purifier sucks in the surrounding air from the top inlet perforations. Air travels through the removable pre-filters placed at the top of the machine, which catch and trap larger airborne particles and dust.
A powerful fan pushes the pre-filtered air down into the cylindrical shaped H13 HEPA filter located in the middle of the unit. The fan creates high static air pressure in the cylinder, which is necessary to allow sufficient air to flow through the high quality H13 HEPA filter and to boost air cleaning capacity.
3. HEPA H13 FILTER
As air hits the H13 HEPA filter, bacteria, viruses and smaller airborne particles and pollutants become trapped on its inner surface and held in place.
4. UVC LIGHT
An 18w UVC lamp placed in the centre of the cylindrical drum continuously illuminates the entire filtration area. The UVC light breaks down the DNA and RNA of pathogens and thereby inactivates them. This continuous disinfection process ensures that the Rensair air purifier is always safe to operate and maintain.
5. CLEAN AIR
Large volumes of clean air travel out of the unit via the lower perforations. The cylindrical shape of the Rensair air purifier allows air to flow out in every direction, enabling effective air circulation suitable for almost all locations.
HEPA filters are mechanical filters with a capacity for sifting small particles at a much higher rate than any other conventional filter. HEPA stands for high-efficiency particulate air and refers to filters made in accordance with specific requirements. Hospital grade HEPA filters are H13 HEPA and above.
UVC light at 254nm inactivates bacteria and viruses by breaking down the DNA and RNA in them, thereby effectively destroying them. The UVC irradiation dose needed for inactivation varies from pathogen to pathogen. Due to Rensair’s patented design, any bacteria or virus caught on the HEPA filter surface will be exposed to a constant and high irradiation dose meaning the filter is continuously disinfected.
In March 2021, the Danish Technological Institute (DTI) conducted rigorous tests on the Rensair air purifier.
The objective of the first DTI test was to determine the unit’s performance in reducing the concentration of Covid-19 particles in the air. The method used active aerosolized MS2 bacteriophages as a proxy for SARS-CoV-2 (Covid-19). The result was a particle reduction rate of 99.98 % in 15 minutes and above 99.99 % in 30 minutes.
The second test was to determine the efficacy of the unit’s UVC light in destroying Covid-19 pathogens on the filter. Again, this used active aerosolized MS2 bacteriophages as a proxy for SARS-CoV-2 (Covid-19). The result was that no virus particles could be detected, thereby demonstrating the effectiveness of the UVC in destroying all traces of the virus.
Rensair destroys more than 99.97% of airborne viruses and bacteria. Eurofins Denmark conducted a test to demonstrate the air cleaning efficiency of the Rensair air purifier.
As a control, an aerosol generator added bacteria and viruses into the air before the air flowed into the air purifier. Prior to being treated by the Rensair air purifier, the air was contaminated with >250 pathogens per m3 of air.
After the treatment, the test results show<1 pathogen per m3 of air. Eurofins concluded that the Rensair air purifier removes airborne viruses and bacteria to undetectable levels.
Norconsult tested the Rensair air purifier technology’s ability to remove airborne particles in a room over time.
“The results show that the air purifier, on its own, cleans the air almost equally efficiently at two selected measuring points in the 93m3 test room and is thus little affected by placement.” and “In a ventilated room [i.e. room with an HVAC system running], the air purifier will also be able to get help from the ventilation system to create full circulation and thus removes particles more efficiently.”

As it does its job, the HEPA filter becomes loaded with contaminated particulate matter. Constant illumination of the filter by UVC light ensures the destruction of all live bacteria or viruses that have been trapped, including Coronavirus. This wholesale destruction has been proven by a test conducted by the Danish Technological Institute, using MS2 bacteriophages as a proxy for SARS-CoV-2.
With all contamination eradicated, the used filter is rendered safe and requires no specialist staff for maintenance.
The Rensair air purifier will run for 9000 hours (~1 year) before the HEPA 13 filter and UVC lamp need to be replaced. A service indicator on the unit’s display panel will automatically alert when the parts need to be replaced.
Changing the HEPA 13 filter and UVC lamp is straightforward and can be undertaken in five minutes.
